Principals behind EB-5 regional centers in Florida have donated more than $800,000 to federal election campaigns.

They donated to George W. Bush. They donated to Hillary Clinton. They have donated to national committees on both sides of the political aisle and to major PACs pushing their agendas.

But nobody has received more than Joe Garcia (pictured above), according to a Herald-Tribune review of government finance records.

Now an industry insider, Garcia is a former U.S. congressman from Miami, who long held a key voice on immigration policy.

Once his political career was over, he joined the EB-5 industry through the Queensfort Capital Florida Regional Center.

The firm, which also operates approved regional centers in New England, is tied to a merchant and investment bank in South Florida.

At least five phone messages left by the Herald-Tribune on the center’s general voice mailbox over a period of several months were not returned.

The EB-5 center is run by Arthur J. Halleran Jr., who serves as the chairman and who claims on his website that he provided input to Sen. Edward Kennedy, who co-sponsored the EB-5 legislation in 1990.

Halleran has donated $60,350 to federal campaigns over the years, including contributions to the company’s eventual senior vice president, Garcia, according to Federal Election Commission records.

Halleran is among those behind EB-5 regional centers across Florida who have donated $42,003 to Garcia’s campaigns — more than they have given to any other federal candidate since at least 1997, those records show.

EB-5 supporter

A Florida attorney and Cuban-American, who previously led the Cuban American National Foundation in Washington, Garcia has long pushed for improved relations with Cuba and for long-term immigration reform that would protect migrant workers and entrepreneurs.

While in office and before joining a regional center of his own, he was an avid supporter of the EB-5 program.

In 2014, Garcia helped introduce legislation that would make EB-5 regional centers a permanent fixture of the visa program, while exempting spouses and children of EB-5 investors from the program’s 10,000-immigrant cap, which would have greatly expanded its impact.

A letter that year from more than 60 members of the U.S. House Democratic caucus said that if the bill had been allowed to come to the floor for a vote, it would pass with “strong bipartisan support.”

After a two-year term, the Democrat from Miami in the U.S. House of Representatives lost the 2014 election amid scandal and left office in January.

Garcia’s former chief of staff resigned and was later found guilty in two separate instances of fraud tied to his boss’ campaigns.

Through various media outlets, Garcia has long denied any involvement in either scheme, and he has never been charged.

Troubled staffer

Jeffrey Garcia, unrelated to the former congressman, began as Rep. Garcia’s campaign manager and became his top staffer.

But his tactics landed him jail for two months for absentee ballot fraud, and as authorities continued to investigate, they concluded Jeffrey Garcia broke another election law through a conspiracy to funnel funds into a straw campaign.

The Herald-Tribune also could not reach Jeffrey Garcia for comment.

In the 2012 election cycle, prosecutors alleged that Joe Garcia’s campaign strategist filed hundreds of phony ballot requests on behalf of voters without their permission — a felony. Authorities say Jeffrey Garcia hoped to use the requests to sway votes from undecided Miami residents.

No votes were stolen in the scheme.

But prosecutors said that Joe Garcia’s top man also had violated campaign finance laws earlier, in 2010 — a campaign run in which he was defeated.

In that case, Jeffrey Garcia was found to have conspired with friend Jose Rolando Arrojo to put together an erroneous Tea Party campaign in Arrojo’s name, part of an attempt to take conservative votes away from Joe Garcia’s primary Republican contender.

An eight-page filing in federal court in Miami outlines how Jeffrey Garcia was behind contributions to Arrojo’s Campaign for Congress that exceeded election law limits.

He was sentenced to two years of probation, with eight months of home confinement and a $1,000 fine, according to federal court records. Arrojo was also charged in the scheme.
